| Abstract: | Photocatalytic process is one of the current technology with high efficiency and economizing energy for the removal of pollutant from water. Recent progress on surface modifications of TiO2 doped by metal cation and metalloid anion has been summarized,based on the findings reported in the present literatures. The cause which ions doped in TiO2 improve photocatalytic activity of TiO2 has been explained according to the mechanism of ion modification,and being faced with problems and developing prospects of photocatalytic process are set forth. |
